1898, Sheng Da Cotton Mill officially broke ground on Taozhu Dam of Tangjiazha, west of Tongzhou, and was completed and put into operation the following year. Guangsheng Oil Factory, Fuxing Flour Factory and Zisheng Metallurgical Factory were established in Tangzha, and the industrial zone of Tangzha Town was gradually formed. At the same time, a port, Tiansheng Port, was built along the river west of Tangzha, and a school was set up. Tongzhou Normal School is the first normal school in China, and its construction marks the beginning of the specialized organ of normal education in China. Zhang Jian advocated "saving the country through industry" and "saving the country through education" before his death, and organized many factories, enterprises and educational and cultural undertakings. Although his "saving the country through industry" could not save the old China in peril, it was beneficial to the social, economic and cultural development at that time.
